Features and specs

What each product offers, as listed by its team.

Crystal (programming language) 5 features
PermitCore.dev 6 features
  • Performance
    Crystal is designed to have the performance of C, thanks to its compilation to efficient native code. Its static type system and low-level memory management capabilities allow optimized execution.
  • Syntax
    Crystal offers a syntax that is heavily inspired by Ruby, making it intuitive and familiar for Ruby developers. This can significantly reduce the learning curve and improve developer productivity.
  • Type Inference
    Crystal provides powerful type inference, enabling developers to write less boilerplate code while still benefiting from the safety and performance of a statically-typed language.
  • Concurrency
    Crystal supports lightweight concurrency with fibers, which allows developers to write efficient and scalable concurrent programs with a simpler syntax compared to traditional threading models.
  • Community and Ecosystem
    Crystal has an active and growing community. It also boasts a rich ecosystem with libraries and tools, making it easier for developers to find resources and support.

Possible disadvantages

  • Maturity
    Crystal is still a relatively young language compared to more established languages like Python or Java. This can mean fewer resources, libraries, and tools, as well as potential instability in certain areas.
  • Compilation Time
    Crystal's compilation times can be slower compared to interpreted languages, particularly for larger codebases. This can impact development workflows and iteration speed.
  • Binary Size
    Compiled Crystal programs tend to generate larger binary sizes compared to other compiled languages like Go or Rust. This can be a consideration for resource-constrained environments.
  • Platform Support
    Being less mature, Crystal may have fewer options for platform-specific optimizations and integrations, which could limit its use in certain specialized applications.
  • Tooling
    Although the situation is improving, Crystal's tooling ecosystem is not as mature as those of older languages. This can affect the availability and quality of IDE support, debugging tools, and other development aids.
  • Complete licensing lifecycle
    Create, implement, and sell software licenses from one platform.
  • Built-in License Store
    Sell licenses directly with Stripe automation and no PermitCore sales commission.
  • Flexible license models
    Online, offline, floating, node-locked, subscription, metered, and perpetual licensing.
  • Reseller Program
    Give resellers a dedicated dashboard to track customers, sales, and earnings.
  • Customer Portal
    Customers can view and validate licenses, manage devices, and handle access without contacting the vendor.
  • REST API and six SDKs
    Integrate licensing with .NET, Node.js, Python, Java, C++, or PHP.

Crystal (programming language)
PermitCore.dev

Overall verdict

  • Crystal is considered a good choice for developers who appreciate the syntax and flexibility of Ruby but require the performance and safety of a compiled language. Its balance of readability and efficiency makes it ideal for projects where high performance is critical but developer productivity cannot be sacrificed. However, potential users should consider the relatively smaller community compared to more established languages.

Why this product is good

  • Crystal is designed to combine the elegance and productivity of Ruby with the performance and efficiency of a compiled language. It offers a syntax that is close to Ruby, making it easy to read and write, while its compiler produces highly optimized native code. The language features static type checking, which helps catch errors at compile time, and it comes with powerful concurrency support through lightweight fibers. Additionally, Crystal's extensive standard library and growing ecosystem make it suitable for a wide range of applications.

Recommended for

  • Developers who enjoy Ruby's syntax but need better performance.
  • Projects that require strong concurrency support.
  • Applications where native code performance is a priority.
  • Developers willing to explore a language with a smaller ecosystem.

Questions & Answers

As answered by people managing Crystal (programming language) and PermitCore.dev.

What makes your product unique?

PermitCore.dev's answer:

PermitCore gives software teams one complete path from creating licenses to implementing licensing and selling their product. Developers can generate and manage licenses, integrate them through the REST API or SDKs, and sell licenses directly through a built-in Store without paying PermitCore a commission. It also supports online and offline licensing, floating and node-locked licenses, device limits, entitlements, subscriptions, customer and reseller portals, and Stripe automation. Underneath that workflow is a security model where license keys are encrypted in the browser before storage and usable keys are never persisted in plaintext. A permanent free plan is available for indie developers.

Why should a person choose your product over its competitors?

PermitCore.dev's answer:

Choose PermitCore when you want one platform for the full licensing lifecycle instead of several disconnected tools. You can create and manage licenses, implement licensing through the REST API or SDKs, and sell licenses directly through a built-in Store. PermitCore takes no commission on those software sales. It also covers device management, online and offline use, floating seats, entitlements, subscriptions, customer and reseller portals, and Stripe automation. Browser-side encryption keeps usable license keys out of plaintext storage. PermitCore is EU-hosted, supports Enterprise self-hosting, includes a permanent free plan, and gives every paid plan a three-month free trial.

How would you describe the primary audience of your product?

PermitCore.dev's answer:

PermitCore is primarily for indie developers, SaaS founders, small software teams, agencies, and established software vendors that want one complete path from creating licenses to implementing licensing and selling the finished product. Teams can create and manage licenses, integrate them through the REST API or SDKs, and then sell licenses directly through the built-in PermitCore Store without paying PermitCore a commission on those sales. It supports desktop applications, APIs, developer tools, plugins, and other paid software, with online, offline, floating, subscription, metered, and perpetual licensing. The permanent free plan helps developers get started, while larger teams can grow into reseller management, self-hosting, and custom roles.

What's the story behind your product?

PermitCore.dev's answer:

PermitCore started from a problem we kept running into while building our own software. Adding licensing looked simple at first, but it quickly became another product to maintain: secure key storage, validation APIs, device limits, offline use, subscriptions, customer access, payments, and support all needed their own infrastructure. We built PermitCore so developers could handle that complete journey in one place: create and manage licenses, implement them through an API or SDK, and sell them directly through a built-in Store with no commission taken by PermitCore. What began as an internal solution became a developer platform designed to let other teams focus on the software they actually want to build.

Which are the primary technologies used for building your product?

PermitCore.dev's answer:

PermitCore is built on .NET 10. The backend uses ASP.NET Core, Entity Framework Core, and PostgreSQL, while the administration panel and public website use Blazor WebAssembly. Valkey handles caching and distributed coordination, and the platform is deployed with Docker and Nginx. Stripe powers subscription and Store payment automation. For licensing security, PermitCore uses established cryptographic primitives including AES-256-GCM for browser-side encryption, HMAC-SHA256 for validation, and Argon2/PBKDF2 where appropriate for key derivation and credential protection. Client SDKs are available for .NET, Node.js, Python, Java, C++, and PHP.

Who are some of the biggest customers of your product?

PermitCore.dev's answer:

PermitCore is an early-stage startup, and we do not publish customer names without their explicit permission. Our current users include indie developers, SaaS founders, agencies, and software vendors using PermitCore to create licenses, integrate licensing into their products, and sell licenses through their own built-in Store.
